Claims

[Scope of utility model registration request]

A pair of left and right outriggers 17 are pivotally attached to the frame 16 of the working machine 4 mounted on the vehicle body 5 so as to be able to swing vertically, and a hydraulic cylinder 72 for vertically moving each outrigger 17 is connected to the outrigger 1.
7, an auxiliary step 102 for getting on and off is arranged above the pivot part of the hydraulic cylinder 72, and
The auxiliary step 102 rotates in conjunction with the vertical swing of the hydraulic cylinder 72 between a step usage position X that covers the base side of the hydraulic cylinder 72 from above and a retreat position Y that retreats upward from this usage position X. An auxiliary step device for a working machine characterized in that the auxiliary step 102 is pivotally connected to a frame 16 so as to be vertically movable.
